Improve sign-in link email

[paulwalk]

The email sent with the sign-in "magic" link could be improved in a number of ways:

• Subject line is not clear (currently "Signing in ✨")
• From address is surprising to users ("robot@antleaf.com")
• Email body is plain text - maybe some users expect HTML with branding etc.?)

Tasks:

• Change subject line to "Your sign-in link for the International Repositories Directory (IRD)"
• Investigate cheapest way to get a better "from" email address associated with an SMTP account that IRD can use.

Email "from address" now adds the name "IRD" to the "robot.antleaf.com" address. Most email clients will display the IRD. This is a pretty good solution which avoids paying for and maintaining a new email address.

I will also look at using the support@antleaf.com address instead of the robot@antleaf.com address as a "friendlier" address

Now using the email address "support@antleaf.com" which is a friendlier address, but anyway email address also now has a name - "IRD" - which is what appears in most email clients.

It look like this in Mac Mail:

I think this is sufficient, so propose to close this now.

@mkshearer - what do you think?

Hi, I think this solution is much more friendly and familiar for clients.
